5668 2022-01-20 East End PAR Sensor Undercanopy Moved East End PAR Sensor Diffuse Moved locations at EE from undercanopy PAR 1 to dfPAR on top of the tower
5229 2021-03-30 Lab none Installed East End none Installed in EE wetland to measure undercanopy PAR. This sensor is SE of the tower mounted on a horizontal boom. The sensor is sitting on top of a fallen bundle of dried reeds.

4646 2020-07-28 Vaira PAR Sensor Incoming Cal Moved Vaira PAR Sensor Reflected Cal Moved from the incoming position to the reflected position to continue inter-comparison
4640 2020-06-12 Lab none Installed Vaira PAR Sensor Incoming Cal Installed on the Vaira Tower mounted in the incoming position for cross comparison and eventual swap of the old sensor on the tower for cable repair.
4075 2019-08-27 Lab none Calibration Lab none New calibration factor of 8.30 uV/(umol/m2/s). Tested this sensor at Oxford Tract against AMP reference sensor K&Z PQS1 sn 161073. See RT Report "Oxford Tract Radiometer Comparison - 06/2019" for details.
4534 2018-09-28 Lab none Calibration Lab none Calibrated in the lab by sticking it out the south-facing window in Hilgard 205 with the reference sensor sn 161073. The factory calibration was 8.15 µV/(µmol/m2·s) and the new calibration was 8.47 µV/(µmol/m2·s).
